What Is Globalization? Trade, Investment, and Markets

Globalization is the increasing integration of economies worldwide through trade, investment, technology, and the movement of people and ideas across borders. For four decades — roughly 1980 to 2020 — globalization was the dominant force shaping the global economy: expanding supply chains, reducing costs, opening markets, and lifting billions from poverty. Now, after trade wars, pandemic disruptions, and geopolitical fragmentation, the era of ever-deepening globalization may be giving way to something different.

How Globalization Shaped Markets

Globalization produced enormous benefits for corporations and investors. Companies accessed cheaper labor by manufacturing in developing countries, dramatically reducing production costs. They reached billions of new customers in growing economies. Supply chains became hyper-efficient, optimized for cost rather than resilience. Corporate profit margins expanded as costs fell and revenue opportunities multiplied.

The numbers are striking. Global trade as a percentage of GDP roughly doubled from 1970 to 2008. Foreign direct investment flows grew from $50 billion annually in 1980 to over $1.5 trillion by 2007. Multinational corporations — companies with operations spanning multiple countries — grew to account for roughly a third of global economic output.

For stock investors, globalization was a powerful tailwind. The S&P 500's international revenue exposure grew from roughly 20% in 1990 to roughly 40% by 2020. Companies could grow revenue at rates exceeding domestic GDP by tapping faster-growing international markets. Profit margins expanded as cheaper inputs reduced costs. Diversified geographic exposure reduced vulnerability to any single country's economic cycles.

The Backlash and Retreat

Several forces have slowed or partially reversed globalization. The US-China trade war (beginning 2018) imposed tariffs that fragmented the world's most important bilateral trade relationship. The COVID-19 pandemic exposed the vulnerability of just-in-time, geographically concentrated supply chains — when factories in China shut down, global production halted. Russia's invasion of Ukraine demonstrated that economic integration doesn't prevent geopolitical conflict — and that sanctions can sever trade relationships overnight.

"Reshoring" (bringing production back home), "friend-shoring" (shifting supply chains to geopolitical allies), and "nearshoring" (moving production closer to end markets) have become corporate strategies and government policies. The result: companies are building more redundant, geographically diversified supply chains — more resilient, but also more expensive.

What Deglobalization Means for Investors

If globalization compressed costs and expanded margins, deglobalization may do the opposite — raising production costs, increasing supply chain complexity, and potentially compressing the profit margins that inflated over four decades. This structural shift could put downward pressure on corporate earnings growth and upward pressure on inflation.

However, deglobalization also creates winners. Companies that manufacture domestically gain competitive advantage as import costs rise. Automation and robotics companies benefit as reshoring drives demand for technology that replaces cheap overseas labor. Infrastructure companies benefit from the buildout of new domestic manufacturing capacity.

Quality Investing in a Deglobalizing World

Wide-moat businesses with pricing power are best positioned for deglobalization because they can pass higher costs to customers without losing market share. Companies with flexible, diversified supply chains can adapt to shifting trade patterns more quickly than those locked into single-source dependencies. And businesses whose competitive advantages are rooted in brands, technology, or intellectual property — rather than cheap-labor arbitrage — retain their moats regardless of how global trade patterns evolve.

The quality framework's emphasis on durable competitive advantages is especially valuable during structural transitions like deglobalization. Moats that were built on cost arbitrage (manufacturing in the cheapest location) may narrow. Moats built on switching costs, network effects, and brand power persist regardless of where production happens. Quality investors should distinguish between the two.
